Title: Cleaning out a perforation tunnel using an energised fluid
Inventor: WALTON IAN C
IPC: E21B37/06
Filed: 2008-12-11
Abstract: A method for cleaning out a perforation tunnel 18 involves disposing an energised fluid 65 (such as a foam or liquefied gas) in a formation 60, and reducing pressure in a region of the wellbore below the pressure of the surrounding formation to liberate a gas in the energised fluid 65 near the tunnel 18 created in the formation 60. A tool 62 with an openable chamber 52 may be used to create the low pressure region.

Title: Optical pulse propagation
Inventor: HARTOG ARTHUR H
IPC: H04B10/2519
Filed: 2006-06-07
Abstract: A method for propagating short optical pulses comprises constructing a composite pulse (22) comprising a probe pulse (10) flanked by a pair of guard pulses (16, 18) of different wavelength from the probe pulse. These pulses have respective temporal delays so that the composite pulse has a central portion in which the intensity is substantially constant with time. This protects the probe pulse from self-phase modulation (SPM) during propagation of the composite pulse through an optical fibre; only the external edges of the guard pulses undergo SPM. After propagation, the guard pulses are filtered out, leaving an undistorted probe pulse for detection. In some embodiments, the composite pulse contains a plurality of probe pulses, which may have different wavelengths. Various apparatus can be used for generation of the composite pulse.

IPC: C01B7/01
Filed: 1966-03-08
Abstract: A process for decomposition of chlorinated hydrocarbon residues with recovery of HCl comprises atomizing the residues, containing not more than 75% by weight Cl, into a combustion furnace at 600 DEG  C. at least; burning in enough O2 or air to obviate soot formation while steam or water is introduced into the furnace, in amount at least half the Cl content of the residues by weight, to avoid evolution of Cl2 gas; and absorbing the HCl in water or dilute hydrochloric acid. The residues may be atomized by means of O2 and/or air and/or steam, and the steam or water may be introduced into the furnace in admixture with air for combustion. Residues which contain more than 75% Cl may be diluted before decomposition with chlorine-free hydrocarbons or hydrocarbons which contain less chlorine.

Title: Improvements in or relating to diode lasers

Abstract: 1,147,850. Diode lasers; PN junction devices. TURLABOR A.G. 4 March, 1968 [7 March, 1967], No. 10421/68. Headings H1C and H1K. A PN junction diode laser has a portion 10b of surface 10, from which radiation is emitted, made opaque or diffusive. The object is to prevent rays 18 reflected in directions not parallel to the plane of the junction being transmitted through surface 10 and producing interference fringes in the far-field image by interference with beam 13. The crystal 1 may be of gallium arsenide with a tellurium-doped N-region and a zinc-doped P-region, and portion 10b may be roughened or covered with an opaque coating, or covered by a separate shield. Portion 10b should extend as close to the junction region 8 as is possible without disturbing output beam 13, a distance of 4Á being mentioned. If surface 9 is partially transmissive a similar opaque or diffusive portion may be provided thereon. It is stated that roughening of the surface 10a of the P- region is unnecessary when using gallium arsenide since light rays are strongly absorbed therein, but may be required with other materials.
Patent GB-351583-A (GB)
Title: Treatment of rosin and product thereof
IPC: C09F1/00
Filed: 1930-04-02
Abstract: Bleached gum-rosin or wood-rosin is heated below the decomposition temperature in order to reduce the tendency to crystallization.  With wood-rosin the treatment also reduces the content of the potential colour bodies which in the process of sizing paper give a yellowish colour on solution of the rosin in alkali and subsequent treatment with aluminium salts.  The heating is carried out at a temperature between 260 DEG  C. and 325 DEG  C., the period varying accordingly from 8 hours to 10 minutes, for example 2 hours at 300 DEG  C., as described for crude wood-rosin in U.S. Patent 1,643,276.  The process may be applied to rosin which has been lightened in colour by any known method, such as distillation in vacuo, extraction with solvents, treatment with stannic chloride or other salts, or filtration through fuller's earth. Besides destroying the potential colour bodies and reducing the tendency to crystallization, the process removes part of the remaining colour, reduces the water content of wood rosin, and increases the optical rotatory power in naphtha.  The optical rotation may be used as a test for the tendency to crystallize, and may be increased by the process to + 20 or even + 32 for gum rosin, or to + 40 or over for wood rosin.  Rosin, treated as described, is altered chemically so that on distilling off 1 to 10 per cent in vacuo under a fractionating column, a residue of high melting point and viscosity is obtained, specially suitable for lacquers and in making cores for foundry work.

Title: Electrically-controlled switching circuit
IPC: H03K17/00
Filed: 1965-03-12
Abstract: 1,097,836. Semi-conductor switching circuits. DANFOSS A.S. March 12, 1965 [March 13, 1964], No. 10656/65. Heading H3T. [Also in Division H2] A switching circuit comprises at least two junctionless non-rectifying solid state switches 9, 10, 11 connected in series, each capable of switching from a high resistance to a low resistance condition on application of a voltage in excess of a threshold value and of reverting to the high resistance condition when the current passing through the device falls below a holding value, and a corresponding impedance 12, 13, 14 connected in parallel with each solid state switch and of such a value as to permit the passage of holding current for the remaining switches when that switch is in its high resistance condition. As shown, a control pulse applied from 3 via transformer 6 to a capacity coupled electrode 15 of switch 9 causes it to conduct and the switch remains conductive after the pulse has finished since the capacitors 13, 14 provide a current path to the switch from the supply 1 the current flowing being sufficient to maintain the switch conductive. The switches 10, 11 are similarly caused to conduct and for A.C. operation the control pulse circuits are coupled to the supply so that the switches are caused to conduct at the correct intervals. In an alternative arrangement (Fig. 3, not shown), the switches are caused to conduct by a control pulse applied in parallel with the entire solid state switch connection. This circuit has a choke (30) connected between the switches and the supply to provide protection against an over voltage of the supply and to prevent control pulses from passing to the supply. The solid state switches can be produced from a mixture of tellurium and elements from Groups IV and V of the Periodic Table. The threshold values can be set as required by suitable selection of the mixture proportions or the thickness of the switch body.
